Abstract:This study deals with a solid oxide fuel cell- gas turbine (SOFC-GT) hybrid system coupled with a multi-effect evaporation desalination plant with steam condensation. The environmental evaluation is also done due to the importance of waste energy recovery especially waste heat in power generation systems. The evaporation desalination plant is studied for using the excess heat to produce freshwater. The thermodynamic relationships governing different components of the system are first provided, including fuel c… Show more
“…Alternative or renewable energy can be derived from sustainable sources such as solar energy, geothermal energy and chemical energy conversion sources and other types. [1][2][3][4] Some existing renewable energy sources are dependent on natural externalities, such as solar or tidal energy, which limits their permanent use. Electrochemical cells are considered to be one of the technologically sustainable energy sources.…”

“…Upon anodic polarization of the La 1−x Sr x Co 1−y Fe y O 3−d electrode, the concentration of oxygen vacancies on the electrode surface decreases signicantly, resulting in the inhibition of Sr segregation on the surface and at the electrode/electrolyte interface. 248,251 The decrease in oxygen vacancy concentration can be described by eqn (4).…”
This review focuses on recent advances in the study of segregation processes, namely modeling, segregation on single and polycrystalline samples, effects of polarization, interdiffusion, different atmospheres and exsolution of nanoparticles.

“…Different solar energy treatment options for wastewater treatment are electrolysis, 12 photo-catalysis, 13 microbial desalination, 14 advanced oxidation process 9 and desalination. 15,16 Beside other technologies, solar desalination can prove to be most cost-effective, efficient and promising for the treatment of wastewater for freshwater generation with fewer contaminants.…”
The escalation in demand for textile products increased the use of fresh water and treatment of wastewater; which escalates the search for suitable and energy-efficient technology for wastewater treatment. Solar assisted technology ( i.e. solar desalination) for the textile industry wastewater treatment is proved to be an affordable technology. The only drawback of solar desalination is its low productivity which is the major hindrance in the global acceptance of the system. In the present study, an ingenious improvement in form of a parabolic concentrator-based solar desalination system (PCB-SDS) is designed to overcome low productivity, and the simultaneous use of source textile industry wastewater for its treatment makes this study more realistic. The performance of the designed system was examined for three different brine depths i.e. 20%, 40%, and 60% for two different processing step i.e. Dyeing and Degumming. System performance was evaluated in terms of energetic, exergetic, pollutant removal, and economic analysis. The maximum output of the system was found to be around 7440 and 8330 mL/day on clear sunny days with textile dyeing wastewater (TDyWW) and textile degumming wastewater (TDgWW) at 60% depth respectively. Daily average energy and exergy efficiency of system varies in the range 39.8–51.9 and 3.6–4.8% respectively. The degumming wastewater shows 85% COD removal, whereas, around 90% of TDS and hardness removal was also recorded. The dyeing processed wastewater showed 80% COD removal efficiency, ≅90% TDS, and hardness removal. The cost per liter of distillate output produced from designed PCB-SDS was found to be 0.014 $/L.
